how to support create two h264enc on dm365

yangchar

hi,

 i want to encode one video stream twice with different resolution,and will encode to jpeg file,should i create two h264 codecs?like follow config file:

var MPEG4ENC = xdc.useModule('ti.sdo.codecs.mpeg4enc.ce.MPEG4ENC');

var H264ENC = xdc.useModule('ti.sdo.codecs.h264enc.ce.H264ENC');
var JPEGENC = xdc.useModule('ti.sdo.codecs.jpegenc.ce.JPEGENC');
var G711ENC = xdc.useModule('viga.sdo.codecs.g711.G711ENC');
var SPEEXENC = xdc.useModule('viga.sdo.codecs.speex.SPEEXENC');
var Engine = xdc.useModule('ti.sdo.ce.Engine');
var myEngine = Engine.create("encode", [
    {name: "mpeg4enc", mod: MPEG4ENC, local: true, groupId: 1},
    {name: "h264enc", mod: H264ENC, local: true, groupId: 1},

    {name: "h264enc2", mod: H264ENC, local: true, groupId: 1},

    {name: "jpegenc", mod: JPEGENC, local: true,groupId: 1},
    {name: "g711enc", mod: G711ENC, local: true},
    {name: "speexenc", mod: SPEEXENC, local: true},
]);

i create two h264enc in two differrent threads,and got this:

CMEMK Error: Failed to find a pool which fits 56
CMEM Error: getPool: Failed to get a pool fitting a size 56
Error: Failed to create video encoder: h264enc2

i you want get more info tell me，thank you.

Hi Yangchar,

Pl solve CMEM allocation issues by adding required pool in loadmodule.sh, and run the encoder with codec debug library to get the reason codec creation failure. To run the codec with debug library link your app with h264venc_ti_arm926_debug.a lib OR rename h264venc_ti_arm926.a to h264venc_ti_arm926_production.a and h264venc_ti_arm926_debug.a to h264venc_ti_arm926.a.

Thannks,

Veeranna

hi Veeranna，

thank you so much to answer my question,and i think i should tell you more details:

i work in dvsdk_2_10_01_18 and my h264 codec and jpeg codec version are H264ENC.version.01.00.00.18.wizardversion.0.5.2 JPEGENC.version.01.00.00.05.wizardversion.0.5.2, i did not see h264venc_ti_arm926_debug.a,so i change h264 codec to H264ENC.version.02.10.00.06.wizardversion.0.5.2, but i got the same error print info:

root@192.168.4.230:/opt/viga# ./encode -v enc.264 -s enc.spx -j enc.jpg

]);

i'm realy confused why the cmem need a pool fitting a size 0?

BTW，the encode can work with two H264ENC and H264ENC+JPEGENC,but when i run two H264ENC+JPEGENC i got this error; and i also change the H264ENC and JPEGENC run in parallel(link),i alse got this message.

wish you can replay me soon.

Hi,

Pl solve CMEM errors before this, once you solve those you will not get such a error. As you are going to create 2 encoders so requirement of pool will be more, so please allocate enough pools.

Thanks,

Veeranna

hi,Veeranna

i'm so sorry,i don't understand what PI means?and i think i have allocated enough pools,thanks.

Hi,

I am sorry not being clear. I meant there cmem pool errors before zero size error. I wanted you to fix them. And in log I am not seeing any codec related error to cause codec creation failure.

Thanks,

Veeranna

hi,Veeranna

i really did what you want me to do,i add pools like this:

pools=4x56,16x384,16x1344

but i got error print messages like

CMEMK Error: Failed to find a pool which fits 384
CMEM Error: getPool: Failed to get a pool fitting a size 384

so i don't know what to do next,and thank you so much.

Hi Yangchar,

You can use heap for the codecs by making ALG_MEM.useHeap = true; in alg_server.cfg file.

Also you should NOT have 2 entries for H264 encoder in the codec engine config table.

But you can create multiple instances of the H264 encoder.

Anand

Hi, Anand

It's works,thank you so much,but i want to know why can't i create 2 entries for H264 encoder(it also can work)?

Does two entries will cost more resources of CMEM ?
